How to use paste.js
Paste is not limited to the input field. It can also be done with ordinary DOM.
Pasting the text. I can complement it properly.
For contentEditable, font decoration can also be reflected.
You can paste images as well.
When an image is pasted, it becomes a blob and it is expanded. After that you can draw on Canvas etc and upload it to the server. If it is a desktop it seems convenient to copy and paste normally on a web browser.
paste.js is JavaScript open source software (MIT License).
